    I had the same problem once when thumbnailing images for a file editor I made. What you want to do is shrink the images before storing them to memory, and disposing of the source images from system memory once they have been read

    Here is the code I used for mine, it shrinks the images to 110×110, but you can set up your own algorithm to scale it (I believe there is actually already a function for that within the resizedbitmap class, but I havent used it)

    public void setImageFromFile(String filename) {
    ImageView fileImage = (ImageView)findViewById(R.id.file_image_holder);
    Bitmap icon = BitmapFactory.decodeFile(filename);
    int width = icon.getWidth();
    int height = icon.getHeight();
    int newWidth = 110;
    int newHeight = 110;
    float scaleWidth = ((float) newWidth) / width;
    float scaleHeight = ((float) newHeight) / height;

    Matrix bMatrix = new Matrix();
    bMatrix.postScale(scaleWidth, scaleHeight);

    Bitmap resizedBitmap = Bitmap.createBitmap(icon, 0, 0, width, height, bMatrix, true);
    BitmapDrawable bmd = new BitmapDrawable(resizedBitmap);
    fileImage.setImageDrawable(bmd);

}
